I don`t know why,even I load the module named "ntils"But the error still hasn't been resolved

I downloaded this project from GitHub and tried to run the test program. My Python version is 3.10, PyTorch version is 2.4.0, CUDA version is 11.8, and I'm using a GTX 1660 Super GPU. However, I encountered many issues.

First, three models failed to download from the server, so I manually added the files "Herbert_base.pt", "rmvpe.pt", and "rmvpe.onnx" by these 3 urls **_(1:https://huggingface.co/Daswer123/RVC_Base/resolve/main/hubert_base.pt ; 2:https://huggingface.co/lj1995/VoiceConversionWebUI/blob/main/rmvpe.pt ; 3:https://huggingface.co/lj1995/VoiceConversionWebUI/blob/main/rmvpe.onnx)_**to the .\rvc-python\base_model folder. Then, when running the program, I encountered the following error: ModuleNotFoundError: No module named 'utils'，after that,I tried to solve the problem again through pip installer ntils, but it didn't seem to work, and in the end, I got stuck in the following error:

I'm not sure if this is a bug or if my environment is incorrect, or if my graphics card selection is incorrect, or if the library hasn't been downloaded properly. Can anyone help me!
lastly,This is my latest code, and the errors shown above are caused by this code.
`from rvc_python.infer import RVCInference

rvc = RVCInference(device="cuda:0")
rvc.load_model("klee.pth")
rvc.infer_file("2.wav", "output.wav")`
I hope this can provide some help in solving the problem.
I am just a junior high school student, and there may be some areas that I am not particularly clear about. There may be some simple questions that you think are easy, please understand me，thanks a lot!!!
